WIND EFFECTS. AERODYNAMIC FITTINGS FOR GOODS VEHICLES

WINDSPIEL

Technologists in Europe and America are actively pursuing aerodynamic studies and foresee a great opportunity to improve the efficiency of goods vehicles by relatively simple and inexpensive means which have the effect of improving fuel consumption, acceleration and maximum speed. These devices - of which the topspoiler and the "airvane" are examples - operate by deflection and suction effects on the airflow.
